I disagree. Riddler is absolutely a premier for the general audience, just not as much for the fans. Riddler will get a positive reception depending on the actor and marketing.

I've never heard of anyone ever referring to the Riddler as their favorite character, villain, anything. Among the hardcore fans, Red Hood seems more of a fan favorite to me.

I'm not saying that he won't work at all, I'm suggesting WB push a character that I believe has more potential in Red Hood. If he takes off, thew just expanded the characters that they are marketing. This isn't just about marketing a movie, it's about toys, clothing, books, all the peripherals. They would then be able to push both characters in the future.
